Acid Drainage Technology Initiative (ADTI) Acid mine drainage (AMD) has been a detrimental by-product of coal mining for many years. At present, acid mine drainage continues to pose a potential problem in some areas, despite improved prediction and prevention techniques.

Solutions. Mine Impacted Water (MIW) and other Industrially Impacted Water (IIW) have a serious impact on the environment – it not only damages water and soil systems, but also affects human health, particularly within those communities which are close to active or abandoned mines.

The mining and mineral processing industry is reliant on water for all aspects of their operations. Water treatment and specialty chemical programs are critical to ensuring maximum recovery and throughput while helping to minimize downtime and mitigate environmental, health, and safety risks.

Mining Industry Wastewater Treatment and Metals Recovery. As mining sites continue to expand into remote locations, developers are faced with the challenge of minimizing the impact of large runoff streams and metals-laden wastewater on the local environment.

CHARLESTON, W.Va. –The West ia Department of Environmental Protection has reached an agreement with Patriot Coal Corporation that will set aside more than $50 million for the coal company's environmental cleanup responsibilities.

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks ...

Elpo Treatment Process The "Elpo I Treatment Process" is a proprietary method of treating coal mine drainage involving the addition of a cationic polyelectrolyte to aerated coal mine drainage followed by the addition of a neutra- . lizing agent and a final step of adding an anionic polyelectrolyte.^ Investigators conducting pilot plant ...

From groundbreaking to end-of-life maintenance, today's mining companies face a variety of water treatment challenges that can involve complex permitting, remote operations, and strict discharge limits on water quality.

Mining Water Treatment. Lime products are used to treat runoff and process waters from coal mining, metal mining and non-metal mines. This is accomplished by neutralizing acids from mining waters and precipitating metals and non-metals.

Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without ...
